  • Patent number: 6195108
    Abstract: An image formation apparatus of the present invention forms an electrostatic latent image on a moving photosensitive belt by a laser beam produced by a laser device. A belt edge detector 1 detects an edge portion (belt edge) of a photosensitive belt 100 in a main scanning direction. A virtual edge detection circuit 2 generates a virtual edge detection signal 2A which changes a generation timing in accordance with a change of a detection timing of the belt edge detected by the belt edge detector 1. The generation timing of the virtual edge detection signal 2A does not almost follow the detection timing of the belt edge which changes by flaws and non-linearity of the belt edge, and changes in accordance with a slow change of the detection timing. A synchronizing signal generation circuit 3 and a driving circuit 4 drives the laser device so as to start a writing of an image data by the laser beam in synchronization with the virtual edge detection signal.

  • Patent number: 5835120
    Abstract: Light emitted from an array of light-emitting elements in an electrophotographic printer is transmitted through a birefringent plate that deflects light polarized in a first plane but does not deflect light polarized in a second plane perpendicular to the first plane, and through a polarization switching device that is controlled by an electrical signal so as to selectably transmit light polarized in either the first plane or the second plane. The transmitted light illuminates a photosensitive medium. Each light-emitting element can illuminate two dots on the photosensitive medium, depending on the state of the polarization switching device, thereby doubling the dot resolution.
